Description

Technical Field

[0001] This utility model relates to a rotating shovel for a shovel-type transport vehicle, belonging to the technical field of shovel-type transport vehicles. Background Technology

[0002] With the development of technology, shovel-type transporters have been gradually applied in coal mines. They are mainly driven by diesel engines and used for the overall lowering of hydraulic supports into the longwall mining face (in inclined shafts) for relocation and face-changing operations. They allow for rapid loading and unloading of supports and offer flexible driving and operation. However, existing shovel-type transporters primarily use a fixed shovel structure. Since some operations require steering, the entire vehicle body needs to be rotated to complete the steering action. However, in the confined spaces underground, where steering is not possible, operation becomes very cumbersome and inconvenient. Utility Model Content

[0003] To address the technical problems existing in the prior art, this utility model provides a rotating shovel for shovel-type pallet trucks that is simple in structure, easy to use, and can greatly improve handling efficiency.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a rotating shovel for a shovel-type transport vehicle, comprising a fixed shovel and a movable shovel. The movable shovel is mounted on the fixed shovel via a rotating support member. Control pull rings are respectively installed on both sides and the rear of the movable shovel. The fixed shovel is provided with a positioning hole, and the movable shovel is provided with a positioning pin, which is used to be inserted into the positioning hole.

[0005] Preferably, the rotating support includes a support ring, a rotating ring, and support rollers. The support ring is installed in the middle of the surface of the fixed shovel plate, and the rotating ring is installed in the middle of the bottom of the movable shovel plate. The rotating ring is inserted into the support ring, and the rotating ring is provided with an annular support plate for supporting itself on the support ring. Multiple support rollers are also evenly distributed on the circumference of the support ring. The support rollers are fixed on the fixed shovel plate and supported on the bottom of the movable shovel plate.

[0006] Preferably, an annular baffle is also installed on the outside of the support ring, the annular baffle is fixed on the fixed shovel plate, and the support roller is disposed between the annular baffle and the support ring.

[0007] Preferably, an annular lubricating oil groove is provided between the support ring and the rotating ring, and the annular lubricating oil groove is composed of semi-circular grooves provided in the inner ring of the support ring and the outer ring of the rotating ring.

[0008] Compared with the prior art, the present invention has the following technical effects: The present invention has a simple structure and reasonable design. It adopts a movable shovel plate that can be rotated on a fixed shovel plate. The movable shovel plate can rotate flexibly on the fixed shovel plate, which can greatly improve the working efficiency in the well and make it more convenient to use. Attached Figure Description

[0012] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0013] like Figures 1 to 3 As shown, a rotating shovel for a shovel-type transport vehicle includes a fixed shovel 1 and a movable shovel 2. The movable shovel 2 is mounted on the fixed shovel 1 via a rotating support. Control pull rings 3 are respectively installed on both sides and the rear of the movable shovel 2. The fixed shovel 1 is provided with positioning holes 4, and the movable shovel is provided with positioning pins 5, which are used to be inserted into the positioning holes 4.

[0014] This invention employs a movable shovel plate 2 mounted on a fixed shovel plate 1 via a rotating support. Multiple control rings 3 are arranged around the movable shovel plate 2, which control the rotation of the movable shovel plate 2, facilitating underground operation. The fixed shovel plate 1 and the movable shovel plate 2 are positioned together by a positioning pin 5, which can be locked when rotation of the movable shovel plate is not required.

[0015] The rotating support component includes a support ring 6, a rotating ring 7, and support rollers 8. The support ring 6 is installed in the center of the surface of the fixed shovel plate 1, and the rotating ring 7 is installed in the center of the bottom of the movable shovel plate 2. The rotating ring 7 is inserted into the support ring 6, and an annular support plate 9 is provided on the rotating ring 7 for support on the support ring. Multiple support rollers 8 are evenly distributed on the circumference of the support ring 6. The support rollers 8 are fixed on the fixed shovel plate 1 and supported at the bottom of the movable shovel plate 2. The rotating support component 6 is centered within the support ring 6 supported by the rotating ring 7, and the multiple support rollers 8 support the movable shovel plate 2, ensuring reliable and stable rotation of the movable shovel plate and sufficient load-bearing capacity.

[0016] In addition, an annular baffle 10 is installed on the outside of the support ring 6. The annular baffle 10 is fixed on the fixed shovel plate 1, and the support roller 8 is disposed between the annular baffle 10 and the support ring 6. The annular baffle 10 can prevent large particles of debris from hitting the support roller, ensuring smoother rotation of the support roller. An annular lubricating oil groove 11 is provided between the support ring 6 and the rotating ring 7. The annular lubricating oil groove 11 is composed of semi-circular grooves disposed on the inner ring of the support ring and the outer ring of the rotating ring. The annular lubricating oil groove 11 can lubricate the support ring and the rotating ring, ensuring flexible and labor-saving rotation between the support ring and the rotating ring.

[0017] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model shall be included within the scope of the present utility model.
